Guys, I need a little help here. These few days, I've been experiencing weird screen artifacts appearing on my macbook screen. I've took picture with my phone and you can check it on the attached files. I have been looking for the problem in the google and read about how macbook pro retina 15" early 2013 are experience screen problem and I wonder if i'm experiencing the same problem. Anyone can help me? will be much appreciated, thanks !
